IMPROVEMENT IN GANG-TACKI NG MACHINES.

Specification forming part of Letters Patent No. 214,754, dated April 29, 1879; application filed January 31, 1879.

To all whom it may concern:

Be it known that we, MATTHIAS BRooK and ERASTUS WOODWARD, both of Boston, in the county of Suffolk and Commonwealth of Massachusetts, and CEO. W. COPELAND, of Malden, in the county of Middlesex, in said 'Commonwealth, have invented an Improvement in 'vided with horizontal adjustment in relation to each other to a line coincident with the edge of the last bottom or insole, and with vertical adjustment to the slopes, ourvatines, or inclinations of a lasts bottom; third, a reciprocatin g driving-bar for each nozzle; fourth, means for lateral adjustment of the nozzles and driving-rods; fifth, means for vertical adjustment of the nozzles and driving-rods.

In the drawings, Figure 1 represents a perspective view of a section of our machine for driving two tacks into position upon the last. Fig. 2 is a side elevation, showing the manner of supporting and moving the device and its position when removed from the-last. Fig. 3 is a side elevation of a section of nozzles removed from the driving mechanism. Fig. 4 is a plan of the blocks carrying the nozzles. Fig. 5 is a plan to illustrate the method of securing the removable nozzle-frame to the rest of the machine. Fig. 6 is a view, part in elevation and part in section, of the driving mechanism, showing the means for horizontal and vertical adjustment. Fig. 7 is a view, in elevation and section, showing the construction. Fig. 8 is a side elevation of seven sections, representing the invention as applied for the entire side groups.

I The post A, carrying the swinging bracket B, which supports the tack-driving mechanism, may be secured to the lasting-machine proper, or to a bench, or any suitable support, in .such close proximity to the lasting-machine that the tacking device may be swung into place upon the last.

The driving mechanism is suspended from the bracket 13 upon the sleeve C, which is pro vided with a vertical adjustment in the bearing 1) at the end of the bracket, regulated in extent by the position of the collar 0 and the set-screw 0 The bearing 1) is composed of the two parts I), which encircle the spindle or sleeve, and almost but not quite abut, and they act in connection with the screw-lever b as a clamp. The sleeve is provided with a the brackets 0 which furnish the bearings c for the short shaft d, which carries the camprojection D on the disk (1 The revolution of the disk causes the cam-projection to con-- tact with the projection 6 upon the slotted bar c and thereby lift the cross-plate E, carrying the driving-rods in opposition to the drivingspring 0 which surrounds the rod 0 within the sleeve C.

The lower portion of the sleeve C is provided withrecess 0 extending across the same, whose sides act as guides in connection with that part of the bar el which reciprocates therein.

The nozzles F are supported by the blocks F which have a horizontal movement in the frame F, by means of the racks f and pinions f The pinions are provided with long bearings upon the operating-shaft f, and they revolve with the shaft sufficiently to adjust the nozzles by moving the blocks, but allow the shaft to continue its revolution after the nozzles have so been adjusted. They have a loose bearing upon the shaft, and are clamped thereto between the clamping-collars f f, the nut f regulating the extent of the clamping action.

It is desirable that the pinions should revolve sufficiently to adjust the nozzles horizontally by moving the blocks,'anol this can only be obtained by giving them such a bean ing on the shaft as described.

Each block is further provided with'the projecting ways f which fit intothe corresponding recesses f in the inner surface of each of the side frames f. The nozzle or throat F is formed by or attached to the lower end of the sleeve 'or tube f the driveway extending from one end of the tube to the other. These tubes have a vert-ical'movement in the blocks F to an extent regulated by the collar and setscrew f to effect the vertical adjustment of the nozzle. I

The upper end of 68.0.; driveway-tube is provided with a bracket, f which carries at its end the adj usting-rodf which passes through the hole 0 in the projection 0 upon the driving-rod blocks.

Attached to each end of theframe carry- I ing the nozzle-blocks is the guiding-rod F which is notched at its upper en d at f These rods, when the section is in place, pass through holes in the corresponding ends of plate E, which reciprocate thereon, and the latches 9 en gage with the notches, and prevent the sec-- tion from being removed from plate E.

The latches are each pivoted at g and connected with each other by the rod 9 and the spring '9 which lays hold of the rod and is fastened to the plate, serves to automatically maintain the latches in position over the holes through which the rods F pass, except when pushed aside by the rods as they are passed through the holes. To enable this to be done i the sides of each latchwhich projects over the hole 'is' undercut, so that the end of the rod as itpasses through the hole strikes an inclined surface and forces the latch oneside.

The driving-rods H are each fastened to the blocks h, arranged to slide horizontally inthe plate E. For this purpose the plate isprovided with an undercut recess, h, the inclined sides of which serve to retain the blocksh,

.with .corresponding. shaped sides, in place,

and also act as guides. The outer end of each of these blocks h is recessed to straddle the rods F I I The downwardly-curved piece M, attached to the end of each nozzle by the set-screwm, acts as a guide in determining the relation of I the nozzle to the edge of the bottom of the last or the edge of the insole.

The nozzle or guide maybe provided with a spur, m in which case, by engaging with the. edge of the upper, the adjustment of the nozzles. may be made to assist in drawing the' upper to the last and in maintaining the margin when 'folded in position.

.The under "surface. of the nozzle may be roughened" in order to insure its taking hold; of the upper with'sufficient friction to prevent its slipping thereon.

Tacks may be fed to the nozzles by the re moval of the section represented in Figs. 3

311(14 from the machine, and the depositing of a tack from a feeding device into eacli of the'driveways, to fall through said driveways upon the converging supporting-springs at the bottom of each nozzle.

descent of the driving-rods.

The section thus charged is replaced in the machine, and the tacks are then driven by the Each may be provided with the feedway P opening upon its side, into which a tack may be dropped to a position below the driving-rod by any suitable device.- p

We do not intend, however, to confine'ourselves to the method of feeding herein described, but propose to use, in connection with the mechanism herein set" forth, any desirable means for intro'du'cing'tacks, either from a reservoir of loose tacks or several from tack- ,Strips, and presented by automatic mean-s to a position in the driveway or nozzle beneath the driving-rods.

It will be observed that two adjustments are essential in the employment of this invention for a side-group tacking device for use in the lasting process, growing out of the differences in width and height of the surface of the last and insole, and 'it is necessary that each nozzle should have-these adjustments independent of the others, and we have therefore provided each nozzle with the following adjustments: first, vertical adjustment, in order that'the nozzles may correspond to the varying planes of a lasts surface; second, horizontal adjustment for variations in widths.

The first of these adjustments is obtained by giving the tube containingthe driveway a vertical movement in the supporting-blocks. The

second is obtained by means of the pinions and racks described, which, byturnin g the handle at the end of shaft f independently, adjust each nozzle in relation to the edge of the last or insole by causing each nozzle carr'yin g block to be moved horizontally until the'curvedgage or stop at the end of the nozzle contacts with the side of the last or edge of the insole and setsthe same in. proper relation to said edge;

In the operation, the last having been properly jacked in a lasting-machine and the upper fitted thereto, and its margin folded upon the surface of the insole by lasting appliances, the tacking device is swung into place across the last, locked to the lasting-machine, and-its nozzles adjusted horizontally.

They automatically assume the necessary 1 vertical adjustment by gravity. .The disk carrying :the operating-cam is then revolved, and

the plate which carries the driving-rods is justment in their supporting-blocks h, either,

automatic or otherwise. v, I

The principal features of the invention, therefore, are the drivingoftacks in groups and the independent vertical and horizontal adjustment of the nozzles and the advantage arising from its use over single-tack-driving machines is the saving in time effected in driving a given number of tacks, and for lasting purposes precision in placing tacks.
